In terms of absolute capacity, CF’s fuel system has plenty of flow.
It’s way better than 85 seconds at 6psi....... so, fundamentally it’s fine.
At this point I’m just seeing if there is a way to adjust the regulator differently so there isn’t a 2psi system pressure drop when going from idle (9psi) to wot at rpm (7-ish psi)........ to try and minimize the float drop.
If none of that seems to have any impact on the laying down in high gear...... then the “what I would do” test would then be put the Demon completely back together, put it back on and verify that with the same bowls, and the floats adjusted the same way...... it doesn’t lay down 1/2 way thru high gear(after pulling strong through the first two gears).
